I know people think there is absolutely no reason for doing this and I am not here to stir up that debate. I am just curious if anyone knows what happens (from experience or second hand) to rigs that convert the 4.0 Fuel injected rig to a Carburetor. As I understand it, it is a fairly simply conversion, you just have to replace the intake and exhaust manifolds from an older 4.2 setup, with some modification. I thought it was cool that the engine does not need a new head.
I assume there is some trick to making sure fuel flow is regulated properly but that can be figured out.
My question is: how is engine timing regulated in this case? Would you still need a working MAP sensor connected to the ECU? That can't be because the injectors are all gone. So what controls engine timing. Perhaps I am just unaware of an existing timing chain or belt?
The idea is to downgrade to no computer or sensors. Yes, I know this is a DOWN-grade. Just curious if it would work in theory and if anyone has done this.
I have no plans to do this. Just a flight of fancy.
